Sloped Aluminium Coping Solutions – Precision Water Management
In roof and parapet design, proper water management separates adequate protection from exceptional performance. Our engineered sloped aluminium coping systems take passive protection a step further by actively directing water away from vulnerable building edges through precisely calculated angles. Unlike flat copings that rely solely on overhangs, our sloped profiles (available from 5° to 25°) work with gravity to keep walls dry, even during torrential downpours.
The science behind our sloping systems begins with hydraulic calculations tailored to your specific location’s rainfall intensity data. Our technical team determines the optimal angle considering: roof size, exposure rating, and adjacent materials. The aluminium profiles then undergo CNC folding to create perfectly consistent angles along entire runs, with integrated anti-capillary grooves that break surface tension to prevent water tracking back underneath. This attention to detail results in 40% better water clearance compared to standard flat copings in independent testing.
Particularly effective for low-pitch roof applications, these sloped systems solve common issues like ponding water at parapet walls or staining on light-coloured façades. The range includes specialised versions for different scenarios: our 15° Snow Relief profile features a steeper back slope for northern sites, while the 7° Urban profile provides subtle drainage in space-constrained city locations. All maintain the same concealed fixing system as our standard copings, preserving clean architectural lines while adding this enhanced functionality.
Installation requires careful planning that our team supports through:
-
Site-specific slope direction diagrams
-
Pre-formed corner units matching your chosen angle
-
Laser-levelling marks every 500mm
-
Expansion joints sized for the pitch
For retrofit projects, we’ve developed innovative adjustable brackets that allow slope introduction to existing flat copings without full replacement. This has proven particularly valuable in resolving long-standing damp issues in 1960s-80s apartment blocks where original specifications underestimated rainfall intensity.
